FABRIC-ROLL-EDGE PROTECTOR.

Specification of Letters Patent.

Patented June 27, 1911.

To all whom it may comm.-

Be it known that L'GEORGE J. OLTSOH, a citizen of the United States,residing at South Bend, in the county of St. Joseph and State ofIndiana, have invented certain new and useful Improvements in Fabric-Roll-Edge Protectors, of which the following is a specification.

The object of this invention is to provide means for effectivelyprotecting the ends of fabric rolls against damage during shipment andhandling of the same, and at the same time to serve as a closure for theends of the bore, within which, as in the case of roofing material,packages containing nails or tacks and cement for applying the roofingare placed, and thereby prevent their displacement and loss.

Another object of the invention is to provide a fabric roll edgeprotector which is simple in structure, easily applied and held inposition without the use of a tie rod commonly employed for the purpose,with a consequent saving in cost of manufacture and labor in applyingthe same.

With these and other objects in view, the invention consists of certainnovel features of construction as hereinafter described and pointed outin the claims, it being understood that minor changes of constructionmay be made without departing from the spirit of the invention, orsacrificing any of the advantages thereof.

In the drawings, which show the pre ferred embodiment of the invention:-'Figure 1 is a longitudinal sectional view of a fabric roll, showingmy improved protector caps applied to the ends thereof. Fig. 2 is a sideView of the cap. Fig. 3 is a sectional view taken on the line wa: ofFig. 2; and Fig. 4 is a perspective view of the expansion disk.

Referring now more particularly to the accompanying drawings, theprotector cap comprises a rim portion 5, which is adapted to abutagainst the end of the roll and protect the edge of the fabric againstdamage. Extending laterally from said rim portion are a plurality ofyieldable fingers 6, arranged in a circle to fit the bore'of a fabricroll, and in the formation of which, the cap being preferably formedfrom a single sheet of metal, a central opening is formed throughthe-rim, as indicated at 7. The fingers converge at their free ends, and

are bent or crimped to form shoulders 8 and 9, and theirinwardlyextending edges given outer sides of the fingers snugly fittingthe bore, and their free ends being yieldable and converglng, may beeasily forced into place so as to have a tight fit. A wooden disk .11,having a diameter such as to provide a close fit with the openingthrough the cap, 1s passed through said opening and is forced agalnstand part the inner shoulders 12 on the fingers, in doing which thefingers are spread or expanded lnto binding engagement with the fabric,as lainly'shown in Fig. 1, the spread of the ngers being such as to givethe same, taken as a whole, a wedge formation, with the larger endthereof at the inner end, and effectively locking the cap againstaccidental displacement. The disk is forced inwardly a sufficientdistance so that the pointed ends of the fingers will engage theperiphery thereof, and owing to the resistance of the fabric to thefurther spread of the fingers, cause the same to bite into the disk, andlock the same against accidental displacement. It will thus be observedthat any pressure exerted against the disk from within the bore, as bypackages of nails and cement striking there against, which are usuallydeposited therein in connection with roofing material, will only serveto force the pointed ends farther into the disk, as well as spread thefingers the more, thereby securing the cap more firmly than ever. Byforcing the disk inwardly beyond the ends of the fingers, the latterwill be permitted to retract and the cap may be easily withdrawn fromthe roll.

From the foregoing it will be observed that the protector is exceedinglysimple in structure; that the single act of forcing the disk into place,without any turning or other movement whatever, expands the fingers intobinding engagement with the fabric, and the disk into locking engagementwith the fingers, and that the formation of the fingers is such as notto puncture or otherwise damage the fabric, whereby the protector maynot only be easily and cheaply manufactured, but a great saving in timeand labor effected in applying the same to afabric roll.

' Havin thus described my invention, what is claime is 1. Thecombination with a rim provided with yieldable, conver 'ng fingers, of adisk adapted to spread sai the yieldable fingers biting into theperiphery of the disk to lock the latter agamst accidental displacement.

2. The combination with a rim provided with yieldable, conver ingfingers, of a disk adapted. to spread sald fingers, the fingersfingers,the ends of each having a shoulder intermediate its ends and the freeends of the fingers biting into the periphe of the disk-to lock thelatter against acci ental displacement.

In testimony whereof I aflix my signature, in presence of two witnesses.
